Auction Rate Securities

As of June 1, 2013 and March 2, 2013, the Company’s available-for-sale investment securities represented approximately $51.0 million par value of auction rate securities, less temporary valuation adjustments of approximately $2.4 million and $2.0 million, respectively. Since these valuation adjustments are deemed to be temporary, they are recorded in accumulated other comprehensive loss, net of a related tax benefit, and did not affect the Company’s net earnings. These securities at par are invested in preferred shares of closed end municipal bond funds, which are required, pursuant to the Investment Company Act of 1940, to maintain minimum asset coverage ratios of 200%. All of these available-for-sale investments carried triple-A credit ratings from one or more of the major credit rating agencies as of June 1, 2013 and March 2, 2013, and none of them are mortgage-backed debt obligations. As of June 1, 2013 and March 2, 2013, the Company’s available-for-sale investments have been in a continuous unrealized loss position for 12 months or more, however, the Company believes that the unrealized losses are temporary and reflect the investments’ current lack of liquidity. Due to their lack of liquidity, the Company classified approximately $48.6 million and $49.0 million of these investments as long term investment securities at June 1, 2013 and March 2, 2013, respectively.

U.S. Treasury Securities

As of June 1, 2013 and March 2, 2013, the Company’s short term held-to-maturity securities included approximately $481.8 million and approximately $449.9 million, respectively, of U.S. Treasury Bills with remaining maturities of less than one year. These securities are stated at their amortized cost which approximates fair value, which is based on quoted prices in active markets for identical instruments (i.e., Level 1 valuation).

Long Term Trading Investment Securities

The Company’s long term trading investment securities, which are provided as investment options to the participants of the nonqualified deferred compensation plan, are stated at fair market value. The values of these trading investment securities included in the table above are approximately $32.2 million and $28.3 million as of June 1, 2013 and March 2, 2013, respectively.
